    "abstract": "Traditional quantum error correction involves the redundant encoding of k\nquantum bits using n quantum bits to allow the detection and correction of any\nt bit error. The smallest general t=1 code requires n=5 for k=1. However, the\ndominant error process in a physical system is often well known, thus inviting\nthe question: given a specific error model, can more efficient codes be\ndevised? We demonstrate new codes which correct just amplitude damping errors\nwhich allow, for example, a t=1, k=1 code using effectively n=4.6. Our scheme\nis based on using bosonic states of photons in a finite number of optical\nmodes. We present necessary and sufficient conditions for the codes, and\ndescribe construction algorithms, physical implementation, and performance\nbounds.",
